This new thriller follows an investigative journalist (Matt Davis) whose brother disappears after claiming that a certain TV show (also called “Cult”) is out to get him. The premiere episode features a lot of typically good-looking CW actors investigating creepy dark places, and an intriguing performance from Robert Knepper (“Prison Break”) as the cult leader and the actor who plays him. Got all that? Series premiere, 9 p.m. Tuesday on The CW (seattletimes.com/tvlistings).
